Abstract: PURPOSE:To perform the input processing and the output processing in parallel with each other without breaking the contents of a buffer, by monitoring the input/output position of the buffer and generating a halt signal discontinuing the actuation of a device control part in case on idle area exists any more within the buffer. CONSTITUTION:When a trigger signal TXM is turned on ('1'), the data on an address bus 18 are fetched by an address register 40 and compared with the contents of buffer discriminating registers 41 and 42. The data transfer processing is decided and a signal line 51 is turned on when the address value shows an area between (a) and (b). When an R/W signal 20 is turned on (memory read), a gate 42 is opened and the contents of the register 40 are set to an input position register 46. While a gate 49 is opened when the signal 20 is turned off (memory write). Then the contents of the register 40 are set to an output position register 47. A comparator 45 compares the contents with each between registers 46 and 47 and turns on a halt signal line 50 when the coincidence is obtained from said comparison.

Filed: 1997-09-24
Abstract: PROBLEM TO BE SOLVED: To provide liquid crystal shutter spectacles with which a high contrast may be obtd. in the direction of a screen by which stereoscopic images are displayed. SOLUTION: The liquid crystals 1R for the right eye and liquid crystals 1L for the left eye of the liquid crystal shutter spectacles are arranged not within the same plane but with an inclination of about 5 deg.. The high contrast direction in the liquid crystals 1R for the right eye and the liquid crystals 1L for the left eye is directed by this inclination toward the screen of the stereoscopic video display device. The liquid crystals 1R for the right eye and the liquid crystals 1L for the left eye have the same constitution and since their arrangement relations are reversed from each other, the liquid crystals 1R for the right eye and the liquid crystals 1L for the left eye constitute the inclination that both approach toward the face side from the middle of the brow.  Their respective electrode parts 1a eventually exist on the central side (the middle side of the brow) of the spectacles.

Filed: 1989-10-03
Abstract: PURPOSE:To obtain a bright screen which is appropriate for the projection of a projection type television by printing or coating ink in which substance obtained by mixing an A1 scale and a pearl pigment scale coated with titanium dioxide with mica as a base is used as a filler on a plastic film or a sheet. CONSTITUTION:A layer consisting of the ink in which the substance obtained by mixing the A1 scale and the pearl pigment scale is used as the filler is provided on the plastic film or the sheet to obtain a light reflection layer. As the pearl pigment scale, the filler obtained by coating the titanium dioxide with the natural mica as the base is used, and the filler whose coating rate of titanium is 14-43% and whose grain size of the scale is 5-200mum is used. Thus, the bright screen in which reflection brightness is high is obtained. Since a distinct angle is large, an image brighter than that in a conventional manner is enjoyed even in the case that the image is projected on the screen from a projection type television projector which is somewhat lacking in the light quantity of a light source.

Title: Carriage device for shifting arched mobile form device or the like
Inventor: MATSUGASHITA NOBUYUKI
IPC: E04G11/34
Filed: 1990-09-27
Abstract: PURPOSE:To ensure the stable travel and shift of a carriage device with a form device placed thereon, and enable high safety to be maintained for a form shifting work by connecting a pair of carriages for placement on rails in such a way as to freely oscillate vertically, or connecting the enclosures of wheels in such a way as to freely oscillate vertically. CONSTITUTION:Carriage devices 1 are placed on each on a plurality of laid rails 2. Respective wheel enclosures 3 absorb the lengthwise roughness of each travel rail 2. Namely, all the wheels 7 of the wheel enclosure 3 are always in contact with the rails 2, due to the oscillation effect of bearings 8 for the enclosures 3, thereby ensuring a stable travel without floatation. For vertical dislocation between the rails 2, the carriage devices 1 are so connected to each other as to be capable of free oscillation via frame levers 4 and base levers 5 and, therefore, the aforesaid dislocation can be stably absorbed. Also, a form device is made to travel and shift from transverse shift rails to placement rails 6, and placed on two carriage devices 1. According to the aforesaid construction, the carriage devices 1 and the form device thereon can be prevented from exposure to a partial load, and the stable travel and shift thereof can be ensured.
